Electrolytic Decomposition of Water

p {margin: 0; padding: 0;} Eachnlytic Decomposition of water A pair of inent electrodes are dipped into solution by applying a voltage between them results in rapid evolution of bubbles of H2 and O2. Due to very poor electrical conductivity of pure water, a small amount of am ionic state(such as 12204 or Naz 5.04) is added to increase itselectrical conductivity Electrolytes ane chosen such a may that the ions that are Garder to oxidize or reduce than water. Cathode 4Ht(aq) + 4e 2 H2(g) Amode : 21420 O2(g) + 4H+ + 4e Overall : 2th2 O2(g) + 2th (g) Semiconductors It's a substance, usually a solid chemical element or compound that can conduct electricity under some conditions but not others, making it a good medium for the control of electrical current. It has an almost filled valence band, empty conductionband and a very narrow owenergy gap ie, of the order of 1ev. Energy gap of sily Ge ( cy o-Fer
